"STEER_RATIO" into "setup.ini" - how to do it?

alekabul · Sep 3, 2019

Can anyone help me - is there a way to include "STEER_RATIO" from "car.ini" into "setup.ini" and what is in general the convention for the options in "setup.ini"? It would be nice to have it and change the car`s steering ratio while in session from the pits. Your experience or some web links would be greatly appreciated.

I posted this question quite a while ago, I'm not sure If its possible.

I looked with search and didn`t find anything on the topic incl. on the official forum. Seems to be outside of peoples minds altogether. Still can be very useful for drift sessions.

Did you ever figure this out? I'm working on the '71 NASCAR mod, which started life as 540-degree rotation @ 16:1 ratio. I'd love to get the full 900-degree range of my G29, and found a happy place with 30:1 for myself, but I'm sure the series I'll be integrating this into will want to adjust that if possible.

If you have a Fanatec wheel (the older ones; I'm not sure about the DD models), you can touch the tiny button (upper left). go to SEN (a misnomer; sensitivity is something else) and use the adjacent pot to vary the ratio: smaller numbers = faster ratios & v.v. The best thing about this is that you can do it in game, while you're driving.

No guys, I didn't find a way to include it in pits setup screen. I know how the Fanatec wheels work as I'm using GT3RS and Carrera but what I meant is the ability to translate the same 900 degrees into a range of selectable steer locks and it seems impossible. Decreasing the SEN of the Fanatec diminishes the degrees of rotation and that is bad for the steering precision that is required for drifting. In some arcade games it works, not in Assetto.

It occurs to me that STEER_ASSIST sort of accomplishes the said goals, without actually doing it. That's what I plan to integrate. Hope that helps if you're still messing with this!

STEER_ASSIST just makes the ffb less linear, it doesn't change the steering ratio

Right. Seems about as good as we're going to get for now, as opposed to actually being able to set the ratio in the garage. Sucks, but it is what it is.

it makes the strength of ffb less linear, you still have to turn the steering wheel the exact same amount to turn the car. It's not "as good as we'll get" it literally does something unrelated

Okay. OP, feel free to delete my comments. Thought I had helpful info, sorry if it wasn’t.

Increasing/decreasing changes the perceived ratio. That is, the lock-to-lock angularity in the road wheels remains the same, but if you have only 3/4-turn lock-to-lock with the steering wheel, the steering feels very fast; 3 turns lock-to-lock feels very slow. IRL, at Indy, the drivers use a slower ratio in qualy, for precision. In the race, they use a faster ratio for close-quarters combat. Don't sneeze!

Not a matter of sneezing

Just in a drifter with >50 degrees lock I want to be able in setup to select bigger ratios on the rack for normal street driving. That can't be done by decreasing the rotation on the gaming wheel. Seems the only way is to have several versions of "data.acd" at hand and juggle them by renaming in Windows before loading with CM.
ps - Hat off to the drivers that can stay on the limit while using different steering ratios on the same car in a weekend.

About the sneezing - I was just kidding.

any luck trying to add ANY adjustable parameters to setup.ini? im working on my own project trying to add some suspension parameters so i can adjust in the pits and see the results quickly. the stuff im adding just isnt showing up at all. whether i try to make a new tab or add the parameters to an existing tab. when i did the later the entire tab just disappeared. setup.ini seems to not be as straight forward as it appears.

Late reply but for anyone else searching for it, it's in the suspention.ini and no way to get it to the pit setup screen that I know of, the values to tweek is , exampel from a modded SAAB
WBCAR_STEER=0.43981, -0.11922, 0.06899
WBTYRE_STEER=0.10431, -0.09843, 0.06899
Used this to get the car a quicker response. Some time ago I did it so exact how to tweek it is forgotten in my old brain. Just google the Param names and you be on the track.
